Which method is emphasized for communication during an active incident?

The correct choice emphasizes the importance of established communication hierarchies and the use of radios during an active incident. This method ensures that communication is clear, organized, and efficient among all responding personnel. Radios are essential tools in emergency situations, as they provide a reliable means of communication that can operate in various environments, including those where cell service may be compromised.

Established communication hierarchies help to maintain order and prevent confusion, allowing for rapid dissemination of critical information. This structure ensures that commands and updates flow through predetermined channels, which is vital in maintaining situational awareness and coordinating responses effectively among different units or teams involved in the incident.

In contrast, while newspapers and social media can serve informative purposes in non-urgent contexts, they do not provide the immediacy or reliability needed during active incidents. Personal cell phones may also be unreliable due to network congestion or outages during emergencies, making established protocols and devices like radios far more effective in ensuring safe and timely communication.
